Figure 2From: Speaking and cognitive distractions during EEG-based brain control of a virtual neuroprosthesis-armAverage of all brain-control movement trajectories for each subject under different levels of cognitive load. Solid linesā=āNo CL, dashed linesā=āmoderate CL, and dotted linesā=āhigh CL. Colored circles represent the area in which the fingertip had to stay for one second to count as a hit (i.e. circles have a radius equal to the target radius plus the radius of the fingertip cursor).Back to article page
